WATER-CLOSET CONNECTION.

Specification of Letters Patent.

Patented Nov. 5, 1907.

To all whom it may concern:

Be it known that I, JOSEPH J. Cosenovn, a citizen of the United States, residing atScranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Water- Oloset Connections, of which the following is a specification.

This invention has relation to soil pipe connections for metallic water closets, and has for its object the provision of a novel, all-metallic connection between the outlet passage of the bowl of a metallic water closet and the soil pipe.

Heretofore many expedients have been resorted to for the purpose of securing an air tight and water tight connection of the soil pipe to the outlet passage of an all metallic water closet, the one most commonly employed being to interpose between these parts some form of elastic washer, but this type of connection is objectionable, owing to the difficulty of making a tight joint, particularly where the longitudinal axis of the outlet passage is at an angle to the longitudinal axis of the drain pipe, such alinement being difficult to secure, owing to the fact that the soil pipe is placed in position in the fioor during the construction of the building while the water closet is placed in position after the floor has been laid.

In carrying my invention into effect I provide an all-metallic closet with a metallic thimble, which is screwed or otherwise secured in the outlet passage of the closet and projects below the same and seats in a flanged bell or socket attached to the soil pipe, the thimble being spherical on its external surface and the bell or socket being formed with a spherical seat to receive the thimble, the contacting surfaces of the thimble and seat being preferably ground so as to secure a metal to metal contact and an air and water tight joint. In order to connect the bell or socket, carried by the soil pipe, with the closet bowl, I provide the bell or socket with a laterally extending flange, which is pierced at appropriate points for the passage of bolts which pass through said flange and through a flange which is formed integral, with the closet bowl and constitutes the base of the same.

In the accompanying drawing illustrating my invention; Figure 1, is a vertical transverse sectional view of a part of a water closet bowl and part of a soil pipe connected together by means of my improvement. Fig. 2, isa similarview withthe bowl and soilpipe separated. Fig. 3, is a detail sectional view of a portion of a bowl having a modified form of my improvement applied thereto.

The bowl or closet proper is designated 1, and maybe of any desired form and construction and is provided with the base 2, having the depending flange 3, at its edges, this flange resting on the floor 4, and being pierced at 5, 5, for the passage of bolts 6, 6, which carry nuts 7, 7, by means of which the closet is attached to the laterally extending flange 8, formed integral with the bell or socket 9, which latter is carried by the soil pipe 10, being preferably screwed thereon as shown at' 11. The bowl or closet 1, is provided with the outlet passage 12, this outlet passage being located as usual about centrally of the bowl and the lower extremity of the outlet passage is cut away at 13, and the wall of the cut away portion is internally screw threaded to receive the externally screw threaded end of a thimble 14. The bore of the thimble 14, is of the same diameter as the outlet passage 12, so that when the thimble is screwed into place a smooth and uninterrupted joint will be produced.

The thimble 14, and the bell or socket 9 are preferably made of soft metal, that is of a metal which is soft relatively to the closet, the thimble and the bell 0r socket being usually composed of brass, while the closet is of cast iron.

The external surface of the thimble 14, is spherical, as at 15, being formed on the arc of a circle having its center at or about a point X and the bell or socket 9, is formed with a seat 16 which is also spherical and formed on the same are as the thimble, so that the thimble will fit accurately in the seat and, the contacting surfaces being ground, will insure an air tight and water tight joint, whether or not the longitudinal axis of the thimble and the bell or socket are in a straight line one with the other, the thimble fitting the bell or socket in the manner of a ball and socket joint.

In Fig. 3, of the drawing I have illustrated a modification of my invention and in the construction shown in this figure the thimble 14, is fitted into the cut away portion 13 of the outlet passage 12, by a smooth joint devoid of screw threads, being retained in position by soldering or brazing, or by shrinking the walls of the outlet passage around the thimble, or by casting the metal of the closet around the thimble. In Fig. 3, I have also shown a modification of the manner of securing the bell or socket 9, to the soil pipe 10, the connection in this figure being effected by a wiped joint 17, instead of the screw connection 11, illustrated in Figs.

'1and2.

I claim:.

and formed with a spherical seat and a thimble having one end externally screw threaded and screwing into the outlet passage of the closet and the other end spherical, said spherical end fitting the seat in the hell or socket.

3. The combination with a water closet composed of hard metal, a soil pipe, and a soft metal bell or socket carried by the soil pipe and formed with a spherical seat, of a soft metal thimble secured to the water closet and projecting below the same, the projecting end of the thimble being spherical and contacting directly with and fitting the spherical seat in the hell or socket.

4. The combination with a Water closet having an outlet passage, of a thimble carried by the closet at the end of the outlet passage said thimble having its projecting end of spherical form on its external surface, a soil pipe and a hell or socket carried by the soil pipe and formed with a spherical seat, to receive the rounded or spherical end of the thimble.

5. The combination with a Water closet bowl having a base flange adapted to rest on the floor and having a spherical thimble screwed into its outlet passage, of a bell or socket having a spherical seat and a floor flange, the said thimhle being adapted to contact withthe seat in the hell or socket and form a metal to metal connection, while the flanges are out of contactv In testimony whereof I afiix my signature, in presence of two witnesses.
